Should the Tires Be the Same Size on a Trailer that Weighs 5,000 Lbs.

Question

Question:

I bought a concession trailer, which weighs 5000 lbs, it has 2-175 80 13s and 2 - 185 80 13s on it. Is this dangerous or can I tow it with no problems

I would recommend to always match the tires on your trailer. In your case I would recommend the larger 185/80-13 tire size to give you more load capacity.

The tire I would have is the Loadstar ST185/80D13 Bias Trailer Tire - Load Range D, part # AM1ST79. This is a load range D tire that has a maximum load capacity of 1,725 lbs at 65 psi. So four of these tires would give you a total load capacity of 6,900 lbs at 65 psi.

Trailer tires should always be inflated to their maximum psi rating for best performance and longest life.

Answer 1

Trailer tire selection needs to take into account the required tire weight load range for the loaded trailer's weight and also your driving speed. Both the weight load on the tire and your driving speed affect the tire's operating…

Since you have 5.30-12 tires like the #AM10064 we know you need a 12" x 4" wheel. The pilot diameter only matters if you have a hub piloted setup, otherwise there is nothing to worry about as long as it is the same size or larger.…

Answer 3

So there are no 14 inch trailer wheels with a 6 lug bolt pattern, the smallest wheel for that is a 15 inch wheel (this is assuming you have a 6 on 5-1/2" bolt pattern). So you'd have to move to a 15 inch wheel, and the smallest tire that…

It is for the type of tire. Any tire with an R is a radial tire. If you see a D instead, such as the Loadstar ST185/80D13 Bias Trailer Tire w/13" White Modular Wheel - 5 on 4-1/2 - Load Range D, part #AM3S333, it is a diagonal or bias ply tire.…

The next size up from a 4.80x12 is a 175/80-13 which will be around 2.6" larger in diameter and 1.6" larger in width. Therefore, you'll need to make sure you have the space for this new size, but please note the difference will be…

I can end this debate for you real fast! Trailer tires, which will have an ST in front of the size, should always be inflated to the maximum psi indicated on the tire. Trailer tires usually do not have a recommended and maximum psi indication so I am…

We have 3 tire options that are Kenda Loadstar in that size. We have the Loadstar ST175/80D13 Bias Trailer Tire - Load Range D #AM1ST77, the Loadstar ST175/80D13 Bias Trailer Tire - Load Range C #AM1ST76, and the Loadstar ST175/80D13 Bias Trailer…

Answer 8

I cannot say I have ever heard of an R load range trailer tire. Generally, though, the further the letter is in the alphabet the higher the capacity is. If we look at size 175/80-13 then load range D tire #AM1ST77 that you referenced is rated for…

Answer 9

You do not want to mix bias and radial tires on your trailer because they are built differently and will even be slightly different sizes, so the odd tire out will wear differently and both the handling and tracking of the trailer could be affected.…

Answer 11

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Even though I cannot comment specifically on the grease you used because I am not familiar with it, I can tell you the best grease for trailer bearings is a a grease with a rating of GC-LB, which just means it is made to withstand very high…
